Abstract (en)
[origin: US2022077798A1] A supercritical CO2 turbo-generator system is disclosed. The turbo-generator system comprises: a plurality of turbine generator units (200A-200C), a direct current bus (410), a plurality of active rectifiers (290A-290C), and a voltage controller (280). Each of plurality of turbine generator units comprises: a turbine (312) with a supercritical CO2 input and a supercritical CO2 output, a generator (326) with an electrical input and power output, a shaft (314) connecting the turbine and generator, and a speed sensor (327) for determining a speed of the associated shaft. The plurality of turbine generator units are connected in the form of a cascading series with the input of a first turbine generator unit (200A) connected to a source of heated supercritical CO2. The input of a second turbine generator unit (200B) is connected to the output of the first turbine generator unit. The input of a third turbine generator unit (200C) is connected to the output of the second turbine generator unit. The voltage controller (280) is configured to monitor the speed sensor (327) of each of the plurality of turbine generator units and vary the load on each generator (230A-230C) to control shaft (314) speed. Each of the plurality of active rectifiers (290A-290C) then converts the power output of a generator (230A-230C) to direct current, and the power from the plurality of active rectifiers then combined by the direct current bus.
